One or Two, Old or Young?

Hi! I haven't posted on this forum in a while, and forgive me if this is the incorrect section to write this post in.



So, I am rescuing a chinchilla in a few months (so, so excited!) and I was curious. Should I get one, a pair, or a trio? I understand getting one would be easiest for a new owner, but obviously I would like what's best for the chin. I know chins would enjoy some company, as I am at school most of the day, so which would you prefer, single, pair or trio?



I would also like to ask about age. There are rescues from the ages of one year old to fifteen years old - which would be best for a new owner? Does it matter?



Thanks in advance for any replies :)
